SPECIFIGATION forming part of Letters Patent No. 532,448, dated January15, 1895. l Application filed March 30. 1894. Serial No. 505,745-(Nomodel.)

To all whom itl may concern:

' Be it known that I, WILLIAM TAsKER DU# vLANY, .T r., a citizen of theUnited States, residing at New York city, in the county of New York,State of New York, have invented certain new and useful Improvements inElectric-Railway-System Conduits, of which the following is aspecification, reference being had therein to the accompanying drawings.

The objects of my improvements are to provide in connection with twoconductors or trolleywires placed within a conduit and insulatedtherefrom, a trolley standard containing within the wearing plates, atmetal plate conductors made in series with fuse blocks or cut outs aboveand also under the points of contact'of the standard with the slot ofthe conduit, so that if the wearing plate on one side of the standardbecomes cut while a car carrying the standard makes one of its trips,the plate conductor on the opposite side will continue to transmit powerto the motor of said car. l

Another object is to provide the portion of the standard within theconduit with water and mud detlecting shields to protect the fuses ofthe plate conductors and the journals of the trolley and prevent shortcircuiting.

Another object is to provide a cross fuse connection between conductorfuses g g to connect them so that if a section conductor in the conduitbecomes grounded or dead on one side, and the wearing plate Von theopposite sideof the standard becomes worn through and ground7 that thesaid cross fuse connection becomes operative and supplies the necessarycurrent to operate the car motors by crossing the current from right toleft in the conductor plates and vice versa.

Another object in making cross connection between fuses g g is to'supplyfour paths for the current to travel in case of accidents to tb ostandard and conduit system before reaching ,switches for the car:namely, up either one side or both sides of standard if no fuses areburned out and up standard from right to left through cross fuse if thesection fuse of conduit on left side and the lower fuse g and the upperfuse h on the right side of standard are burned and vice versa.

Another obj ect is to divide the conduit system into sections; saidsections being connected through suitable fuses to their respect- Ivefeeder conductors and said feeders are Yconnected at their switch boardterminals with, and made to pass through ampere meters to easilylocalize from said terminal any defect or ground on a section or part ofthe system.

I attain these objects by the construction illustrated in theaccompanying drawings, in which- Figure 1 is a transverse verticalsection of a` trolley standard constructed in accordance with myinvention,said standard having only one of the trolley arms mountedthereon. Fig. 2 is a side view of the lower portion of the trolleystandard. Fig. 3 is a top view of the standard. Fig. 4 is atop view ofthe front (or rear) bar of the standard with portions of the wearingplates and insulated conductors. Fig.. 5 is a front View of the lowerportion of the series of plates constituting the conductors on one sideofthe standard, with the fuse blocks uniting two plates of said series.Fig.

6 is a transverse vertical section of the lower portion of thevstandardshowing a cross fuse connection between the fuses g g to illustrate themethod of`orossing the current from the lower conducting plates c2, tothe upper conducting plates e inthe standard, this modified constructionbeing preferred for the purpose of crossing the currentin saidstandardif one or the other of the section fuses is burned out. Fig. 7 is atransverse vertical section of the track showing the two trolley wireconductors withinv the conduit and the feeder cables of the conductors.Fig. 8 isaplan view of a series of sections of trolley conductors, eachLsection being shown connected with a switch board terminal or amperemeter. Fig. 9 is a perspectiver view of the conduit cleaning brush t0 beattached to the lower end of the Standard.

In said drawings A representsfthe trolley standard, and B the trolleyjournal bearings that are projecting from the sides of the standardadjacent to the bottom thereof and aresecured thereto by means ofllanged cap plates a. The standard consists of side plates kthat arebolted to the front and rear bars K, each of said bars being providedwith a IOO tongue, as shown in Fig. 4 that extends some distance betweenthe plates k, and to which the latter are bolted, the space between thetongues of the bars K and the side plates 7c constituting a rectangularconduit for the reception of the pair of flat conductors e e2 and theirmica insulators f and f 2. The central insnlatorf separates theconductors e and e2 and the insulators f2 protect them from contact withthe side plates 7c and from contact with the tongues of the bars K. Theinner end of cach trolley journal B is provided with a flanged head topermit it to be secured to the plate conductors e2 by means of the capplates a; but upon each journal B and around the flange of; its head isplaced a sleeve b of insulating material that protects it from con-Vtact with the side plates 7a and with the capplates c.

Each conductor consists of two lengths e and c2 that are united togetherby means of fuses (cut outs) g and g2 of any suitable construction. asconsisting of short lengths of wire g3 having one end secured to thecentral portion of the conductor e by wrapping said portion around saidend, while the opposite end is embedded in the easily fusible plug gsecured to the end of the opposite section e2 of the conductor. Thelocation of the fuses g is shown to be at a short distance above thetrolley journals B, and the location of the cross fuse g2 is shown inFig. 6 connecting fuses g to each other. They may be at a higher pointbut said point must be below the location of the wearing plates 7a2, andbeneath the shield J. Said plates 7a2 of the standard are locatedthereon when in use on the level of the edges of the slot of theunderground conduit.

The upper end ot' the standard is received in a metal head-block P, saidblock having pendent therefrom a rectangular sleeve p vthrough whichbolts p2 are made to pass horizontally to engage with the bars K of thestandard and fasten the trolley standard to head block P. The head ofthe block P has bolts p3 passing vertically therethrough to secure it tothe frame of the car. The head block of the standard is also providedwith fuses (cut outs) 7L nearly similar to the fuses g, the electriccurrent passing thence through wires h2 to the switches and motor of thecar.

To prevent mud and water that may be descending upon the standard fromreaching fuses g g or the trolley journals and their arms and producinga short circuit, shields J are bolted to the side plates 7c of saidstandard a short distance above said trolley journals and fusesg g. Saidshields consist of arches formed of angle bars bent suitably with theirouter iiange turned up nearly parallel with the standard, and the lowerportions of said arches extend a suitable distance in front and rear ofthe standard.

The trolley arms d are pivotally mounted upon the outer end of eachjournal B and are They are shown in this instance retained thereon bymeans ol' a washer n and nui n2. Each trolley arm (l is provided withtwo grooved rollers d2 connected in tandem to better facilitate theirpassage over the ends of each independent section conductor in theunderground conduit without interrupting the electric current.

To keep the rollers d2 normally pressed upon the conductor wire, a wirespring C is coiled upon the end ot each journal B andhas one end securedto said journal while the opposite end bears upon the inner end of eacharm d.

Fig. 9 shows a t'an shaped brush Q having a metal back Q2 to be boltedto the bottom or lower end of the standard between its two plates 7cprojecting from the bottom of said standard beyond its conductors forthe pnr-,

pose of sweeping (cleaning) the dirt or mud out of the conduit anddepositing the same in catch basins, not shown, situated at suitabledistances apart and having conduits connecting'both tracks, one with theother. Said conduits are to have a man hole plate between said tracksfor the purpose of better facilitating the removal of the same and toprevent clogging up of the conduits by the dirt, dsc. The back of thebrush has openings a' to receive bolts a2 made to pass through them infastening the same to the plates K of the standard A.

The trolley conduit D has plates D2 on top thereof at a suitabledistance apart to provide between them the slot for the passage of thestandard A; and said conduit has laterally extended bars D3 that connectit with the rails e3 of the track. Said bars rest upon yokeplates M towhich are attached brackets m, the inner ends of which enter the conduitand support insulators m2 for the trolley conductors N. Said bracketsalso carry on suitable standards and insulators m3, the distributingfeeder conductors N2 that carry the electric current from the powerstation to each section ofthe trolley wire ofthe underground system. Forthis purpose the yoke-plates M have large perforations m4 on each sideof the conduit. They have also openings m5 that may be used for thepassage of properly insulated telegraph and electric light wires orcables. The conduit D is provided at suitable distances apart withdrainage pipes d4 that are connected with sewers d5.

To facilitate the detection of any defect in any of the sections of thetrolley conductors N each conductor N is connected by means of itsfeeder conductor N? and through suitable fuses at their switch boardterminal, with, and through ampere meters F preferably love-fed in thepower-house or office of the railway" w line, and thus prevent any carfrom being stalled for any great length of time upon any part of theline as the defect can be immediately perceived and located and repairsbe promptly made by the employs.

Having now fully described my invention, I claim- IIO Mw.. i n
